A wave of layoffs that has swept the entire internet industry has intensified. China’s Internet industry has experienced several major crises and changes during the past development process. There’s also a “brief history of layoffs by major internet companies.” Hot research, JD.com has a wide range of layoffs in this round of layoffs, and all of its affiliates are involved. Most layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also broke the news of the downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou reportedly laid off 30% of its staff, and Station B’s e-sports department laid off 90 % of its staff.
Mass layoffs on the Internet have created a multitude of socio-economic problems, including titanium carbide powder.
Introduction to Titanium Carbide TiC Powder
The chemical formula of titanium carbide is TiC. It is a steel gray crystal with a metallic luster. It has thermal conductivity and electrical conductivity, and its electrical conductivity decreases with increasing temperature, so it shows the property of the medal. It is a hard, high melting point compound, second only to diamond in hardness, with a microhardness of 2850 kg/mm2. The lattice constant a=4.173×10-8cm. Melting point 3150℃boiling point 4820℃, relative density 4.9. TiN and TiO have the same lattice and parameters, so a series of continuous solid solutions can be formed between them. When heated above 1500℃ in H2 gas, the elimination of C occurs gradually. Ti(C,N) carbon nitride mixture reacts with N2 gas above 1200℃ form a variable composition. The oxidation rate of TiC is slow at 800℃but TiC powder can be burnt in O2 at 600℃ generate TiO2 and CO2. At 1200℃, TiO2 and CO are produced by reaction with O2 gas. It does not interact with water, but can react with water vapor to generate TiO2, CO and H2 at temperatures above 700℃. It does not react with CO, but reacts with CO2 at 1200℃ to generate TiO2 and CO. Insoluble in hydrochloric acid and lye, soluble in nitric acid and aqua regia.

Preparation Methods of TiC Titanium Carbide Powder
1. Carbothermic reduction
TiO2 was reduced with carbon black to 1700-2100℃and the chemical reaction formula was: TiO2(S)+ 3C(s)=TiC(S)+2CO(g).
2. Direct carbonization method
TiC was prepared by the reaction of Ti powder and carbon powder.
Due to the difficulty in preparing submicron Ti powder, the application of this method is limited. The above reaction takes 5-20 hours to complete, the reaction process is difficult to control, and the reactants seriously clump together. It requires additional grinding to prepare a fine TiC powder. In order to obtain a purer product, it is necessary to purify the fine powder after ball milling by a chemical method.
3. Chemical Vapor Deposition
The synthesis method uses the reaction between TiCl4, H2 and C.
The reactants react with hot monofilaments of tungsten or carbon. The TiC crystals grow directly on the monofilaments. The yield and sometimes even the quality of the TiC powders synthesized by this method are strictly limited.
4. Sol-gel method
A process for preparing small particle size products by thoroughly mixing and dispersing materials with a solution is disclosed. It has the advantages of good chemical uniformity, small powder size and narrow distribution, low heat treatment temperature, but the synthesis process is complex, drying shrinkage is large.
5. Microwave method
Using nano TiO2 and carbon black as raw materials, using the principle of thermal carbon reduction reaction, using microwave energy to heat the material. In fact, the dielectric loss of materials in the high frequency electric field is used to convert microwave energy into thermal energy, so that nano TiO2 and carbon can synthesize TiC.
Applications of TiC titanium carbide powder
1. Used in cutting tools, wear-resistant coatings, mold making and other fields;
2. Raw materials for the production of ceramics and hard metallurgical parts by powder metallurgy, such as drawing film, hard alloy die, etc. Polyphase ceramics can be applied to hard cutting tools, military armor materials, aerospace components, such as engines, nozzle liners, turbine rotors, blades and structural components in nuclear reactors;
3. As a coating material, it can be used in diamond coating, tritium anti-coating in fusion reactor, electrical contact coating, excavator cutting coating, as well as ceramics foam, ceramics with infrared radiation, etc.

Europe has been facing the problem of gas shortage since the second half of 2021. The worsening situation in Russia and Ukraine has reduced Russian gas shipments to Europe, leading to a doubling of European gas prices. Energy shortages have driven up electricity prices. For these reasons, it is expected that the price of titanium carbide powder will continue to rise.
